We will want to use the Pythagorean theorem
a^2 + b^2 = c^2
We can plug in the values we know
7^2 + 9^2 = c^2
49 + 81 = c^2
130 = c^2
We will then square both sides to get c by itself
c = 11.4 meters

Show that the sum of the reciprocals of three different positive integers is greater than 6 times the reciprocal of their produc

Montano1993 [528]

If a,b,c are the 3 positive integers
1/a +1/b +1/c > 6/abc
(bc+ac+ab)/abc >6/abc so
(bc+ac+ab)>6
The lowest positive integers that are different are 1,2,3 so the lowest value that (bc+ac+ab) could have is 1•2+2•3+1•3=2+6+3= 11 therefore
1/a +1/b +1/c > 6/abc is true

Answer:

See below

Step-by-step explanation:

f(x - 1) is the translation of f(x) one unit right.

So the graph is exactly same shape but shifted right one unit.

f(x) has vertex (-1, 2)

<u>The function y = f(-x) + 2 will have the vertex changed as per rule:</u>

(x, y) → (-x, y + 2)

<u>So the new vertex is:</u>

(-1, 2) → (-(-1), 2 + 2) = (1, 4)
